Abstract

A screed arrangement includes a screed assembly ( 1 ) for laying a road surface ( 3 ), the screed assembly ( 1 ) configured to determine a working width (W), viewed in the working direction (R), for laying of the road surface ( 3 ). The screed arrangement further includes a working station ( 9 ) for an operator (P) mounted on the screed assembly ( 1 ). The working station ( 9 ) is mounted on the screed assembly ( 1 ) in a vibration-decoupled manner, such that the transmission of vibrations from the screed assembly ( 1 ) to the working station ( 9 ) an be reduced or prevented.

First claim

The invention claimed is:

1. A screed arrangement comprising:
a screed assembly for laying a road surface, the screed assembly configured to determine a working width, viewed in a working direction, for laying of the road surface, and the screed assembly including a walkway for an operator; and
a working station for the operator mounted on the screed assembly in a vibration-decoupled manner, such that transmission of vibrations from the screed assembly to the working station can be reduced or prevented, wherein the working station is mounted on a side plate of the screed assembly in order to be associated to an outer area of the working width, and the working station comprises a base plate on which the operator can stand;
wherein the walkway of the screed assembly extends along a larger area of the working width of the screed assembly than the base plate.

2. The screed arrangement according to claim 1 wherein the screed assembly or the working station comprises a mounting unit that detachably mounts the working station on the screed assembly.

3. The screed arrangement according to claim 2 wherein the mounting unit comprises a vibration-decoupling unit that includes at least one mass-spring system and/or a shock absorber.

4. The screed arrangement according to claim 3 wherein the mass-spring system is mounted between the working station and the screed assembly in a preloaded manner.

5. The screed arrangement according to claim 4 wherein a preload force is manually and/or automatically adjustable to the mass-spring system.

6. The screed arrangement according to claim 3 wherein the vibration-decoupling unit includes the shock absorber and the shock absorber has a variable damping hardness.

7. The screed arrangement according to claim 6 wherein the damping hardness is manually and/or automatically adjustable.

8. The screed arrangement according to claim 2 wherein the mounting unit comprises an oscillating bearing by means of which the working station is movable between a stowing position and a working position.

9. The screed arrangement according to claim 1 wherein the base plate is essentially arranged at a same height as the walkway.

10. The screed arrangement according to claim 1 wherein the base plate is arranged on a higher level than the walkway.

11. The screed arrangement according to claim 1 wherein the base plate viewed from above is arranged in alignment with the walkway.

12. The screed arrangement according to claim 1 wherein the working station comprises a seat for the operator.

13. The screed arrangement according to claim 1 wherein the working station comprises a weather roof.

14. The screed arrangement according to claim 1 further comprising a control unit installed on the working station for controlling the working station and/or the screed assembly.

15. The screed arrangement according to claim 1 wherein the working station provides a collision protection unit, by means of which objects approaching the working station can be determined.

16. The screed arrangement according to claim 1 wherein the working station comprises a suction unit, which is configured for sucking off vapors of the road surface to be laid.

17. The screed arrangement according to claim 1 wherein the working station comprises an illumination unit to illuminate an outer area of the working width.

18. The screed arrangement according to claim 1 wherein the working station comprises a heating and/or cooling unit.

19. The screed arrangement according to claim 1 wherein the screed assembly comprises an extension screed with a main screed and extension parts, which are adjustable relative to the main screed sideways to the working direction in order to vary the working width, and wherein the working station is mounted on one of the extension parts.

20. The screed arrangement according to claim 1 wherein the screed assembly comprises a screed with a main screed and widening parts that can be mounted at a side thereof in order to enlarge the working width, and wherein the working station is mounted on one of the widening parts.

21. A road finisher with a screed arrangement according to claim 1 .

22. The screed arrangement according to claim 1 wherein the base plate, viewed in the working direction, extends laterally beyond an outer edge of the walkway.

23. The screed arrangement according to claim 1 wherein the base plate includes an extension that telescopically protrudes into an opening defined by the walkway.
